Question

how can we find the angle of this

Answer 1

do you have any of the side measurements. or a single angle measurement? if so i would break it up into 2 triangles.

Answer 2

@phi

Answer 3

@ganeshie8can you help me

Answer 4

Do you know what d, f and equal to?

Answer 5

* and e

Answer 6

no i totally don't know
i an sending an ttachement

Answer 7

plz tell me how i find the angles using this protractor the angles of quadrilateral

Answer 8

i dont know how should i keep the protractor as in the link the highlighted
HAVE A GO YOURSELF

Answer 9

Are you saying you have a figure on drawn on a piece of paper, and you have to measure each of the angles using a *real* protractor ?

Answer 10

the center of the protractor ("+" sign) must lie onto the vertex of the angle you want to measure

Answer 11

sorry no attachement but i have a link if as i link if i use a protractor then i dont get the sum of 360 and i cheat the answer of above shape of rhombus but i don't know i should i use protractor

Answer 12

in every corner i should use the same way?
ok now i try to do that

Answer 13

and the "0" of the protractor must touch one of the angle sides:

Answer 15

Someone mention me?

Answer 16

yeah tell me above attachment using protractoooor

Answer 17

The diagram you have in your first posting - is that copied from something else?

Answer 18

going away from keyboard - back in 15 minutes

Answer 19

i want to know about this above attachment that is using protractor

Answer 20

i also want to know quadrilaterls making 4 angles whose sum is 360 but i am not getting 360 perhaps don't know the use of protractor as in above link MATH IS FUN...

Answer 21

Gone longer than I thought.

Generally speaking in geometry, trig and so on you rarely have to measure or draw angles with such precision. Quite often, it can all be done mathematically.
For example, for a right triangle that has one side 3 and another side 4, we can determine the hypotenuse by the Pythagorean theorem:
hypotenuse² = 3² + 4² = 25
hypotenuse = 5
Then if we wanted to know the angles, we can say
arc tangent Angle A = 4/3 = 1.3333333
Angle A = 53.13 degrees

arc tangent Angle B = 3/4 = .75
Angle B = 36.87 degrees

There we have determined the length of one side and the other two angles and we didn't have to draw or measure anything.

Answer 22

Also, it seems in the link you posted
http://www.mathsisfun.com/geometry/protractor-using.html
there are a lot of explanations and videos about using a protractor.
Did you read all those explanations and view all the videos?
